Frequently Asked Questions
Q: What does the 97A durometer rating mean and how does it compare to standard polyurethane wheels?
A: 97A Shore A durometer indicates high hardness on the polyurethane elastomer scale. This rating means SU 653-XL handles abrasive surfaces like concrete better than softer 85A-90A wheels, offering extended wear life in high-mileage operations. The tradeoff is reduced grip on wet or dusty floors. Use 97A for dry warehouse floors, 85A-90A for wet food processing environments.
Q: Is the upgraded SU S653 XL-A variant a direct bolt-in replacement for SU 653-XL?
A: Yes, SU S653 XL-A is a direct upgrade. It shares identical 5.000 inch diameter and 2.875 inch width, with the same 1.87 inch bore. The XL-A version adds reinforced bearing shoulders and improved load distribution for sustained heavy-duty use above 4,000 pound rack capacity. All mounting bolts and spacing are identical - no frame modification required. Upgrade cost is typically 15-20 percent higher but lifespan increases to 30+ months.
Q: Can I mix SU 653-XL wheels with different hardness ratings on the same truck?
A: No. Mixing different durometer wheels causes steering instability and uneven load distribution. Always replace wheels in complete sets of four. If one wheel fails prematurely, inspect the frame for alignment issues or bent axles before installing replacement. A single failed wheel often indicates underlying suspension damage that will destroy new wheels within weeks.
